A roller bearing is located between the flange 21 and the inner end of the recess 12. This bearing comprises an inner ring 24 and an outer ring 25. The lateral edges of the outer cylindrical surface of the inner ring 24 are beveled oil, as shown at 26, for purposes to be described in connection with the cage. Interposed between the rings 24 and 25 are the rollers 27, said rollers being mounted within a cage and said cage being cheaply and conveniently formed from pressed or cast metal made in two complementary parts so shaped'as to form pockets for the rollers and to provide means whereby the parts may be conveniently assembled and, when so assembled, the rollers and cage will remain in place between the rings 24 and 25 without any liability to end thrust upon the rollers and cage. This cage, as will appear more a particularly from the detail views onSheet 2, consists of two symmetrical sections 28, each section having a plurality of halfpoclrets 29 therein which, when the sections areconnected, form complete pockets where in the rollers are retained in such manner as to bear aginst the inner and outer rings 24 and 25 and to roll freely within the pockets. Between the half pockets 29, the metal of the cage sections is deflected or pressed in a directionsubstantially parallel to the length of the rollers, to form reentrant recesses 30, the bottoms of which recesses are flattened, as shown at 31, thereby forming abutting surfaces or flanges for the cagesections, permitting said sections to be secured together, through such flanges or surfaces, as by means of rivets The parts are so proportioned that the lateral faces of the cage sections will not project beyond the lateral faces of the rings 24 and 25, and, in order to prevent any displacement of the cage and rollers with respect to said rings, the inner edges of the lateral faces of the cage sections are beveled, as shown at 33, complementarily to the beveled surfaces 26. g

A roller bearing of the type just described is shown applied to the recess 12 with the rings 24 and 25 abutting against the lateral surfaces provided on each side of the recess 23 and with the inner lateral face 0t the ring 24 abutting against the flange 4. The-roller bearing is retained in place in the recess by means of an end thrust ring 34, screwed into the inner end of the recess 12, said ring being recessed at 35 to provide clearance for the 1x" cage and having a bearing surface an ed to abut against the adjacent lateral S1 "ace of the outer -.ring 25.

37 denotes a generally frusto-conical collar which surrounds the corresponding portion 3 of the spindle and is provided with a cylindrical extension 38 at its outer end.

The collar 37 is provided with a radially projecting flange 39, the inner surface of which forms in effect a continuation of the.

inner surface 1O of the flange 10 said inner surface being adapted to take the lateral thrust of the ring 16. The outer end of the collar 37 is in alinement with theshoulder 13 Surrounding the outer end 2 of the spindle and located in the seat provided between the outer end of the ring 37, the washer 8, the recess 13 at the outer end of the hub 11 and the inwardly projecting flange 15 of the dust cap, is a smaller roller bearing identical in construction with the larger one shown at the inner' end of the hub, the corresponding 'arts of the bearings being designated by hkernumeralfsa The washer 8 is provided with a recess 8} to provide clearance for the cage of thisbearing and with a surface 8 adapted to take the lateral thrust of the ring 24.

With the hub mounting constructed as described, it will'be evident that the roller bearings provided at'the inner and outer ends of the hub will takethe radial thrust only; that the lateral thrust will be taken by the ball bearing comprisingthe parts 16 to 20; that on a movement of the hub inwardly this thrust will be transmitted from the flange 10 diagonally across the balls 19 to the radial flan e 21, and that on a movement of the hub outwardly, the thrust will be transmitted diagonally across the balls 19 fromthe radial flange to the flange 39 of the collar 37; and that the-parts 34 and the flange 15 of the-dust cap. F urthermore, it will be apparent that the roller bearings are not only capable of withstanding all radial thrust exerted thereupon, but,

by their construction and the construction of the cooperating parts, the rollers are absolutely protected against lateral thrust and that the rollers of these bearings are positively retained in place without any liability to displacement.

Having thus described myinvent-ion, what I claim is:

1. In a roller bearing, the combination of an inner bearing ring, a two-part cage-comprising symmetrical sections each havin half-pockets therein adapted to receiverolE ers therewithin, with inwardly projecting portions between said halfockets adapted to abut and provide means or securing said sections together, an outer bearing ring adapted to surround the inner ring and the cage, one of said rings having beveled edges and the cage having beveled edges overhanging and coacting with the beveled edges of the ring, the cage sections being adapted for assembly from opposite sides of said bearing, substantially as s ecified.

2. In a roller bearing, t e combination of an inner bearing ring, two-part cage comprising symmetrical sections each having half-pockets therein adapted to receive rollers therewithin, the metal of the cage sections between said pockets being deflected inwardly to form reentrant recesses, said recesses extending inwardly from the outer Eeriphery of each section and having their ottoms abutting to provide means for securing said sections together, an outer bearing ring adapted to surround the inner hearing ring and the cage, the inner ring having beveled edges and the inner unbroken periphery of each cage section being beveled to overhang and cooperate with a beveled edge of said ring, the cage sections being adapted for assembly from opposite sides.

In testimony whereof, I hereunto aliix my 30 signature in the presence of two witnesses. MARCELLUS REID.
